Military police head General Abdelaziz Jassim al-Shalal announces his defection as the Syrian military struggles to contain rebel advances. Lindsey Parietti reports.

SYRIA'S military police chief has announced his defection from President Bashar al-Assad's regime, accusing the army of having turned into "murderous gangs," in a video posted online.

"I, General Abdel Aziz Jassem al-Shallal, commander of Syrian military police, announce that I am defecting from the regime army, to join the people's revolution," the military-clad officer said.

"The army has deviated from its essential mission, which is to protect the country, and it has morphed into murderous, destructive gangs," General Shallal charged in the video circulated by opposition activists.

"The destruction of cities and villages, and the commission of massacres against our people, defenceless civilians, who took to the streets calling for freedom" prompted Shallal to defect, he said.

General Shallal, whose functions are limited to disciplining soldiers, is not a well-known figure.

The Syrian Observatory for Human Rights cited sources close to General Shallal as saying he was set to retire in January, and its head Rami Abdel Rahman said he has already left Syria, like many other senior military defectors.

According to reports on online platforms, he left Syria for Turkey.

"This man was pushed to the sidelines a long time ago," one Syrian activist said online, adding that General Shallal was "suspected of collaborating with insurgents."

General Shallal "withdrew military police checkpoints from the roads, and he was good to people," another activist wrote online.
